燃烧器常压热态试验动应变测量结果分析
|
摘要
燃烧器常压试验的目的主要是验证设计算法,找到燃烧器工作规律,为修正实压试验、提高产品运行可靠性提供技术准备和运行经验。文章仅对燃烧筒上布置的高温应变片传感器测量出的动应变结果进行了数据分析与评判,研究常压试验过程中脉动压力激振对燃烧筒强度安全性的影响。
The aim of the atmospheric thermal test is to verify the design algorithm,find out the working rules for the combustor and provide technical preparation and operational experience for the modification of the real thermal test and the improvement of the reliability of the products.In this paper,the data analysis and evaluation of the dynamic strains measured by the high temperature gauges which are arranged on the combustor liner are carried out.The influence of the pulsating pressure on the safety of the combustor liner in the atmospheric thermal test is studied.
